Description
Technical field
The present invention relates to the technical field of tail gas filtering more particularly to a kind of washing regeneration tail gas filterings for internal combustion engine
System.
Background technology
Diesel engine is because that good economy, dynamic property, reliability and lower CO, HC (hydrocarbon) are discharged is wide
General application, but the Particulate Emission of diesel engine can reduce particle than more serious by installing particle trapper on exhaust pipe
Discharge.With the growth of working time, the particle in particle trapper filtering body increases, and engine back pressure will rise, and influence bavin
The normal work of oil machine need to be removed these particles by chemically or physically method, i.e. the regeneration of filtering body.
Regeneration techniques are the key technology that can particle trapper work normally on a diesel engine and current micro particle catching
The technological difficulties of device.Divide initiative regeneration and passive regeneration by regeneration.
Initiative regeneration be usually using outside energy improve particle trapper inside temperature, make particle ignition to
It is converted into gas.Or it is regenerated by mechanical systems such as reverse jet, vibrations.Disadvantage is that combustion system, electrical heating system need to be increased
System, high-pressure air source, vibrating device and corresponding control system increase entirety to reduce the reliability of particle trapper
Manufacturing cost and use cost.Each system has that filter core group overheat is burnt, regeneration efficiency is low or can not adapt to vehicle makes accordingly
The problems such as using.
Passive regeneration is made it by using the ignition temperature of certain catalyst degradation particles in normal diesel exhaust gas
At a temperature of ignition decompose.It is realized by major ways such as catalyst coat, fuel oil additives.Current domestic oil product sulphur contains
Amount is higher, can generate toxic action in use to catalyst to make catalyst failure, cause particle trapper can not effectively again
It is raw, it blocks.
Invention content
For the technical problems in the prior art, the purpose of the present invention is：A kind of washing for internal combustion engine is provided
Regeneration tail gas filtration system can make tail gas filtering system reach rapidly and efficiently regenerated effect by way of water flushing.
In order to achieve the above object, the present invention adopts the following technical scheme that：
